BWP Setup RT Uplink

The features described in this topic apply to the M9484C VXG only.

Bandwidth part (BWP) is a UE-specific setting, but VXG signal generators do not have a concept of UE. Therefore, separate BWP setups are required so that each data channel can select which BWP to use.

BWP_ID

Applies to the M9484C only.

Displays the ID of current BWP, it is automatically generated based on the index of the BWP array.

Name

Applies to the M9484C only.

Sets the name of the BWP. It is used to select the BWP for the data channel.

Numerology

Applies to the M9484C only.

Displays the numerology used by the BWP. Numerology specifies the subcarrier spacing and cyclic prefix definition used for this bandwidth part. Numerology affects symbol duration and the number of subcarriers possible for a given carrier bandwidth.

RB Offset (N_BWP_start)

Applies to the M9484C only.

Sets the RB offset of the current bandwidth part (BWP) relative to CRB0.

A resource block (RB) consists of 12 contiguous subcarriers. The RB Number determines the contiguous amount of spectrum available to the specified BWP, starting from the RB Offset within the containing component carrier. The maximum number of RBs potentially available to this BWP is determined by the numerology of this BWP and the maximum RB limit specified for the component carrier for that particular numerology.
